Suppose a study estimated that 61% of the residents of a community (with an
error range of 18 percentage points at 95% confidence) favor replacing the
playground equipment. Which of the following percentages of the
community's residents may favor replacing the playground equipment?

A. 82%
B. 54%
C. 72%
D. 95%

Answers

Answer 1

Finding the confidence interval, it is found that the percentages of residents that may favor replacing the equipment is be given by:

B. 54%.

What is a confidence interval?

The interval is given by the estimate plus/minus the margin of error. The range is twice the margin of error.

In this problem, we have that:

The estimate is of 61%.Since the range is of 18%, the margin of error is of 9%.

Hence the interval is given by:

(61% - 9%, 61% + 9%) = (52%, 70%).

Each of the values in the interval can be the percentage, hence option B is correct.

Jeanette earn $33 in 8 hours. At the rate, how much would she earn in 5 hours?

Answers

Answer:

If you made $33 in 8 hours, then you should divide 8 into 33 to see how much you make per hour. 8÷33= (explaining how to get answer) can 8 go into 3? No. put a zero on top of the first three. Now can 8 go into 33? yes, 4 times, 4×8= 32, so we have 1 left over. add 2 decimals to the number so that it is $33.00, (still that same number just with zeros on the end). So far the answer is $04.??. How many times can 8 go into 10? 1 time with 2 left over, so write the one on top of the .0! Now with 2 left over we have to see how many times 8 can go into 20, 8×2= 16 16+8=24, so it can only go in 2 times without going over 20. Now that we have rounded it up to 2 decimals we don't have to keep going and your answer is

$4.12 times that by 5 and you will get the final answer.

Write a rule in both coordinate notation in vector notation to represent the translation of a parallelogram to the right

Answers

The rule in vector notation for the translation to the right is described by the following formula:

[tex]V'(x,y) = V(x,y) + (9, -4)[/tex]

Vectorially speaking, a translation is described by the following expression:

[tex]V'(x,y) = V(x,y) + T(x,y)[/tex] (1)

Where:

[tex]V(x,y)[/tex] - Original point.[tex]V' (x,y)[/tex] - Translated point.[tex]T(x,y)[/tex] - Translation vector.

By direct inspection we see that parallelogram C'D'E'F' translated to the right is moved 9 in +x direction and 4 in -y direction. Hence, the translation vector is equal to:

[tex]T(x,y) = (9, -4)[/tex]

And the rule in vector notation for the translation to the right is described by the following formula:

[tex]V'(x,y) = V(x,y) + (9, -4)[/tex]

Answers

Answer:

134 people

Step-by-step explanation:

80 / .6 = 133.333

Answer:

134 people

Step-by-step explanation:

we can use cross multiplication to solve this problem:

we know that 60% is 80 people and 40% is x people (we put x because we don't know the exact number of how many people yet)

now we set it up:

[tex]\frac{80}{60}[/tex] = [tex]\frac{x}{40}[/tex]

= 60x = 3200

= x = 53.33333

now we add the two numbers of people up:

53.33333 + 80 = 133.3333

since it is a decimal, it would be safer to assume that there are 134 people

Answers

[tex]\\ \sf\longmapsto GI=8.22[/tex]

If FI = 6 and IH = 12. The length of GI = 8.22.

How to estimate the length of GI?

Given: FI = 6 and IH = 12

To estimate the length of GI

[tex]$\mathrm{Gl}^{2}[/tex] = FI (IH)

Simplifying the above equation, we get

[tex]$\mathrm{Gl}^{2}[/tex]= 6 (12)

Remove parentheses: (a) = a

Multiply the numbers then, we get

[tex]$6 \cdot 12=72$[/tex]

[tex]$\mathrm{Gl}^{2}[/tex] = 72

GI = [tex]$\sqrt{72}[/tex]

GI  = 8.22

Therefore, the length of GI = 8.22.
